Abstract (en)

[origin: EP0304124A2] An elastomeric fibre or film prepared from a composition comprising at least one block copolymer containing at least two polymeric blocks containing predominantly monoalkenyl aromatic hydrocarbon monomer units having a weight-average molecular weight within the range from 4,000 to 50,000 and at least one polymeric block containing predominantly hydrogenated conjugated diolefin monomer units having a weight-average molecular weight within the range from 10,000 to 200,000, a relatively low molecular weight polymer selected from the Group consisting of anionic styrene homopolymers, alpha-methylstyrene homopolymers, hydrogenated styrene, copolymers of alpha-methylstyrene and styrene and mixtures thereof and may contain a wax. In particularly preferred embodiments, the elastomeric fibre or film will contain at least one A-B-A triblock copolymer and an A-B min diblock copolymer. In even more preferred embodiments, the elastomeric fibres or films will contain at least two A-B-A triblock copolymers and at least one A-B min diblock copolymer.
